     - /experimental/: if you build ~mu~ with [[https://github.com/CLD2Owners/cld2][CLD2]] support (available in many Linux
       distros), ~mu~ will try to detect the language of the body of e-mail
       messages; you can then search by their ISO-639-1 code, e.g. ~mu find
       lang:en~
 
+    - set the default database batch-size (the ~--batch-size~ parameter to ~mu
+      init~) to 50000 rather than 250000; the latter was too high for systems
+      with limited memory.

+    - restore expansion for "~--option=~/foo~" type options for shells that don't

     - In the main-view, by default ~q~ is now bound to ~mu4e-main-quit-or-bury~,
